My Keyport and mousebad is not working?

My Keyport and Mousepad is not working. This starts two days ago, today it was function but now it´s againe not working? I have to use a external keyport and a external mouse now.

I tried already to restart the my computer, but this does nothing to the problem...

and before I had several times the problem that my MacBookpro doesn´t react on the keport and mousepad, but when ever that was, I just did a restart and it was working...

Check the ribbon cable under the trackpad.

(between the battery and topcase). There's a "known issue" with the routing of the cable over the battery and through a guillotine like slot in the lower case. Using the keyboard hammers the ribbon cable in the slot and can losen, or short that cable.

Quick fixes are:

  1. Simply flattening the cable by turning over the MacBook and pressing on it.
  2. Placing a folded scrap of paper or note between the cable and the topcase.
  3. Replacement of the ribbon cable.

Good Luck,

N.

LOL. This actually helped me too. I think what worked on my now about 9 year old MacBook (with no battery installed) was massaging the black plastic pad under the touch pad. So, thanks!

This line of MBPs unfortunately has a record of failing topcases. I think it's some issue with the cicuitboard under the trackpad, which manages keyboard, trackpad and TP button. I never found another way fixing this than replacing the entire topcase. The keyboard can likely be reused.

Bummer, Apple!
